Why Drinking Alcohol After a Concussion Is a Risk Athletes Can’t Afford to Take
When a concussion occurs, the brain undergoes a range of physiological changes, making recovery a delicate process that requires careful management. It is crucial for athletes recovering from a concussion to avoid alcohol.
Despite the temptation to celebrate a victory or cope with the emotional stress of being sidelined, consuming alcohol post-concussion can significantly hinder the healing process and lead to a host of complications.
This article explores why drinking alcohol after a concussion is a risk that athletes simply can’t afford to take, drawing on recent research and expert recommendations.
The Impact of Alcohol on Concussion Recovery
1. Exacerbation of Symptoms
Alcohol consumption can significantly worsen post-concussion symptoms such as headaches, dizziness, and cognitive difficulties. Studies have shown that alcohol can trigger or intensify headaches in individuals with a history of brain injury, likely due to its effects on neurotransmitter balance and dehydration. Additionally, alcohol impairs the brain’s ability to regulate inflammation, which may contribute to prolonged post-concussion symptoms.
For athletes, this means extended recovery times and a greater risk of lingering symptoms that can interfere with both cognitive function and physical performance. Avoiding alcohol during recovery helps ensure that the brain can heal properly without unnecessary setbacks.
2. Cognitive Decline and Long-term Risks
One of the most concerning risks of alcohol consumption after a concussion is its potential to worsen cognitive recovery and prolong neurological impairment. Research indicates that alcohol disrupts neurotransmitter activity and increases neuroinflammation, both of which can compound the cognitive effects of a concussion. Studies on traumatic brain injury (TBI) and alcohol use have shown that post-injury alcohol consumption is associated with slower cognitive recovery, worsened memory retention, and impaired decision-making—all of which are critical for both athletic performance and daily life.

Alcohol consumption after a concussion can make it significantly harder to recognize and diagnose the injury properly. Many concussion symptoms—such as dizziness, confusion, impaired coordination, and slurred speech—overlap with signs of alcohol intoxication, which can lead to misinterpretation of symptoms by both athletes and medical professionals. This increases the risk of delayed or missed diagnosis, preventing athletes from receiving the immediate care they need.
For athletic trainers and other healthcare providers, this poses a significant risk as delayed diagnosis can lead to improper management of the athlete’s condition, potentially worsening outcomes.
4. Increased Risk of Secondary Injuries
After a concussion, balance, coordination, and reaction time are often impaired, making athletes more vulnerable to falls, collisions, and further head trauma. Alcohol’s depressant effects worsen these impairments, significantly increasing the risk of secondary injuries.
Studies on post-concussion motor control deficits indicate that even mild concussions can disrupt an athlete’s ability to maintain stability and react quickly. When alcohol is introduced, these deficits become more pronounced, elevating the likelihood of falls, musculoskeletal injuries, and repeated head trauma.
This risk is not just theoretical. The Characteristics of E-Scooter and Bicycle Injuries report found that alcohol consumption significantly increased the incidence of accidents and injuries post-concussion due to compromised judgment and motor skills.
5. Inflammation, Sleep, and Cognitive Recovery
Alcohol also interferes with sleep quality, which is critical for brain recovery following a concussion. Adequate sleep is necessary for reducing inflammation and supporting cognitive restoration. The study Maxillofacial Injury Patterns in Road Traffic Accidents discusses how alcohol can increase inflammation and disrupt sleep patterns, complicating recovery from head injuries.
Moreover, alcohol’s dehydrating effects can exacerbate post-concussion symptoms like headaches and fatigue.
The emotional toll of a concussion can be significant, often leading to symptoms of depression, irritability, and anxiety. Alcohol, known for its depressive effects on the central nervous system, can intensify these symptoms. The study Social Determinants of Health Influence on Mild Traumatic Brain Injury Symptom Burden found that alcohol consumption post-concussion could lead to more severe and prolonged emotional and cognitive symptoms.
For high school and college athletes, who may already be struggling with the psychological impact of being sidelined, alcohol can worsen mood disorders and delay psychological recovery.
Expert Recommendations for Athletes
The study Sport, Concussion, and Student Subcultures suggests that individuals with suspected concussions should avoid alcohol until they are fully recovered. This recommendation is not just precautionary but is rooted in evidence showing that alcohol can significantly delay both cognitive and physical recovery.
Athletic trainers and other healthcare providers should emphasize the importance of abstaining from alcohol during concussion recovery in their protocols. Educating athletes about these risks and providing clear, research-backed guidelines can play a crucial role in ensuring a full and timely recovery.
Drinking alcohol after a concussion is not just a bad idea—it’s a risk that athletes simply can’t afford. From exacerbating symptoms to increasing the risk of long-term cognitive decline, the dangers are clear and supported by substantial research.
Athletic trainers, directors, and healthcare professionals must work together to educate athletes on the importance of avoiding alcohol during recovery. By making informed choices, athletes can safeguard their health and get back to the game they love faster and safer.
